Benefits of technology

The patent describes a method for automatically putting together a short video based on a video frame set. The method uses an interest frame identification model to identify video frames that match certain conditions. The video frames are then spliced together based on their timestamps to create a short video. This method is efficient and doesn't require too much labor, compared to traditional methods. Overall, it improves the efficiency of creating short videos.

Problems solved by technology

However, since a live broadcasting video lasts a longer time, the manner of manual selection not only can easily miss some highlights, but also is costly, time-consuming and extremely inefficient.

embodiment 1

[0024]FIG. 1 is a flow chart of a short video synthesis method in embodiment 1 of the present application. The present embodiment may be applicable to a case of short video synthesis. The method may be executed by a short video synthesis apparatus. The apparatus may be composed of hardware and / or software, and may be generally integrated in a computer, a server, and all terminals including a short video synthesis function. As shown in FIG. 1, the method includes steps described below.

[0025]In step 110, a video frame set corresponding to a to-be-processed video is obtained, where each video frame carries a timestamp.

[0026]The to-be-processed video may be a video which is recorded by an anchor and published by a live broadcasting platform, or a video (such as a movie video, a television show video, a variety show video, and the like) which is obtained from editing a recorded video by a professional and then is published on a video platform. The video frame set may be a set composed of...

embodiment 2

[0034]FIG. 2 is a flow chart of a short video synthesis method in embodiment 2 of the present application. Based on the above embodiment, as shown in FIG. 2, the method includes steps described below.

[0035]In step 210, a plurality of video frame samples marked with the interest degree label is obtained.

[0036]In this embodiment, the interest degree label includes a label of interest and a label of non-interest. The video frames may be extracted from a plurality of live broadcasting videos on a live broadcasting platform, and the video frame samples may be composed of video frames in a large number of live broadcasting videos. In this embodiment, a process of obtaining the plurality of video frame samples marked with the interest degree label may be to search multiple live broadcasting videos in multiple video categories from a live broadcasting platform, then extract multiple video frames from the multiple live broadcasting videos respectively, and mark interest degree labels on the ...

embodiment 3

[0043]FIG. 3 is a flow chart of a short video synthesis method in embodiment 3 of the present application. Based on the above embodiments, in an embodiment, the step in which all video frames in the video frame set are respectively input into the interest frame identification model to obtain the plurality of to-be-synthesized video frames may be implemented by a step described below. All video frames in the video frame set are respectively input into an interest frame identification model matched with a video category of the to-be-processed video to obtain a plurality of to-be-synthesized video frames. As shown in FIG. 3, the method includes steps described below.

[0044]In step 310, a plurality of video frame samples which corresponds to at least one video category and is marked with an interest degree label is obtained.

[0045]In this embodiment, a video category may be determined by a theme of a video content included in a live broadcasting video, and may include a food category, a c...

Abstract

Provided are a short video synthesis method and apparatus, a device and a storage medium. The method includes: obtaining a video frame set corresponding to a to-be-processed video, where each video frame in the video frame set carries a timestamp; respectively inputting all video frames in the video frame set into an interest frame identification model to obtain a plurality of to-be-synthesized video frames, where the interest frame identification model is used for identifying a video frame meeting an interest degree condition in the input video frames; and splicing, according to the timestamp carried by the each to-be-synthesized video frame, the plurality of to-be-synthesized video frames to form a short video corresponding to the to-be-processed video.
